摘要:
Oscillating and fixing apparatus for oscillating and fixing the recording head in an image forming machine. A recording head records an image on a recording medium which is fed to the record location by a recording medium feeding device. The feeding device has a reference surface. Oscillating apparatus oscillates the recording head toward and away from the recording medium and causes the recording head to abut the reference surface following the forward movement. A fixing device prevents the oscillation effected by the oscillating apparatus and fixes the recording head with respect to the recording medium to protect the recording head from vibration and shock.

A methacrylic resin molding material, comprising a partially cross-linked polymer gel obtained by partially polymerizing a mixture comprising (A) a resin raw material selected from the group consisting of monomeric alkyl methacrylates, .alpha., .beta.-ethylenically unsaturated monomer mixtures formed preponderantly of alkyl methacrylates and a syrup containing at least one of said monomers and at least one of the polymers thereof and (B) 4 to 150 parts by weight of a cross-linking agent based on 100 parts by weight of said resin raw material in the presence of a polymerization initiator, whereby a cross-linked polymer is formed with the aid of said cross-linking agent and said polymerization initiator to the extent that increase of the polymer formed thereby reaches 4 to 62% by weight over the polymer content of said mixture with the total polymer content kept from exceeding the upper limit of 62% by weight said molding material being recovered from the polymerization system as a non-sticky, easy-handled gel-like material which has shape-retaining properties, but which, on the application of shear stress, at normal room temperature or at an elevated temperature, is enabled to flow, and preserved for use in the manufacture of shaped articles.

An ink jet recording apparatus has recording means for discharging ink in response to a recording signal, cap means for covering the ink discharging portion of the recording means, attracting means for attracting the recording means covered by the cap means, and means for inhibiting the cap means from being released from a condition in which it covers the recording means, for a predetermined time after the attracting means has been operated.

A porous sintered body for an aluminum-titanium alloy electrolytic capacitor has a wire of nitrogenized titanium, or the like, implanted therein. A method of producing such a porous body subjects a titanium wire to a nitriding treatment, and embeds the nitrogenized Ti wire into a press-molded body of the mixture of aluminum and either titanium or titanium hydride powders. Then, the press-molded body is sintered. An excellent LC characteristic is obtained even under the sintering condition, and the aluminum-titanium electrolytic capacitor is devoid of bent lead wires.

Disclosed are a catalyst for producing, from an alcohol, an olefin whose number of carbon atoms is at least one more than the number of carbon atoms of the alcohol, wherein at least the surface of the catalyst is substantially composed of zirconium oxide; a method for producing an olefin using the same; and so on.

Provided are a conveying jig, a method of manufacturing the conveying jig, and a method of heat-treating metal rings using the conveying jig. The conveying jig is provided with a base and ten holding shafts raised from the base. Ridges and grooves are alternatively provided in the side wall of each holding shaft. The metal rings are held in position by being engaged in the grooves in the holding shafts. The space enclosed within the holding shafts is communicated with the atmosphere, and this allows, when the metal rings held by the conveying jig are subjected to heat treatment in a heat treatment furnace, an atmospheric gas to circulate in the space enclosed within the holding shafts.

A chamfering apparatus is used to chamfer a peripheral edge of a glass substrate. The chamfering apparatus includes a grindstone having a cylindrical hollow end portion; a grindstone driving unit that rotates the grindstone around an axis of the cylindrical hollow end portion; a substrate rotation-driving unit that rotates the glass substrate around either one of an axis of the outer periphery and an axis of the center circular hole; and a pressing unit that presses the grindstone to the glass substrate such that an annular end surface of the grindstone contacts with an edge of either one of the outer periphery and the inner periphery of the glass substrate while the cylindrical hollow end portion of the grindstone faces with one of the outer periphery and the inner periphery of the glass substrate.
